In this paper, we study adaptive synchronization of chaotic systems where the system parameters cannot be determined accurately. In particular, we focus on the cases of uncertain parameters (i.e. parameters are constant but unknown) and noisy parameters (i.e. parameter values keep fluctuating because of noise). We introduce two different adaptive s...

... q µ (t) is the solution at time t for Van der Pol equation with parameter µ as given by (21). Here λ is the parameter determining the magnitude of the noise and π/4 is Figure 8 shows that the two chaotic systems X and Y synchronize asymptotically. This is particularly interesting since this happens in spite of the parameters being affected by noise generated by another complicated system like a Van der Pol oscillator. ...

The behavior and bifurcations of solutions to three-dimensional (three-phase) quadratic polynomial dynamical systems (DSs) are considered. The integrability in elementary functions is proved for a class of autonomous polynomial DSs. The occurrence of bifurcations of the type-twisted fold is discovered on the basis and within the frames of the eleme...

This paper presents a novel framework for characterizing dissipativity of uncertain dynamical systems subject to algebraic constraints. The main results provide sufficient conditions for dissipativity when uncertainties are characterized by integral quadratic constraints. For polynomial or linear dynamics, these conditions can be efficiently verifi...

We present a representation of skew-orthogonal polynomials of symplectic type ($\beta = 4$) in terms of a matrix Riemann-Hilbert problem, for weights of the form $e^{-V(z)}$ where $V$ is a polynomial of even degree and positive leading coefficient. This is done by representing skew-orthogonality as a kind of multiple-orthogonality. From this we der...

We consider a stochastic version of the so-called Brusselator-a mathematical model for a two-dimensional chemical reaction network-in which one of its parameters is assumed to vary randomly. It has been suggested via numerical explorations that the system exhibits noise-induced synchronization when time goes to infinity. Complementing this perspect...
